Effect of liquid surface tension coefficient on spray cone structure of ejection sprayer

The results of an experimental study of the effect of surfactants on the spatial distribution of droplet concentration in the spray cone of the ejective sprayer are presented. The spectral transparency method and a setup providing scanning the cross-section of the spray cone along its length are used for the study. It is shown that when surfactants are incorporated into distilled water, the radial distribution of the droplet concentration in the spray cone becomes more uniform, and the cone maximum length increases.
